What Kind of Structure Good to Roof PVC Sheet

1. Deck Structure

The surface of the deck should be smooth, the material of the deck should be of small deformation, the deck should be more than 12mm thick (according to the pulin span).

A 3-5mm gap between two decks is essential for deformation. The waterproof rolls should be unrolled smoothly and verically with accurate overlaps.

2. Stell Structure

the angles of steel structure should be precisely controlled during processing, which will influence the pitch of the roof. The deviation of angles will cause an uneven roof.

All the steels should be anti-corrosion treated.

3. Reinforced Concrete Structure

The underlay of concrete has no crucial influence on the evenness of the roof, while the embedded inserts and purlins should be very neat and in a plane.

Both steel and wood embedded inserts and purlins should be anti-corrosion treated to extend the life of roof structure.

Steel purlins should be welded to the steel embedded inserts and wood purlins can be nailed to the wood embedded inserts directly.
